The IcedTea project provides a harness to build the source code from OpenJDK using Free Software build tools, along with additional features such as a PulseAudio sound driver and support for alternative virtual machines.

The IcedTea 2.1.1 & 2.2.1 release updates our OpenJDK7 support to include the latest security updates just released:

We believe that the 2.2.1 release takes IcedTea to the level of 7u5, including both the changes in the public OpenJDK7 repository for u4 and the security updates, which is what we believe u5 is comprised of[*].

In addition, IcedTea includes the usual IcedTea patches to allow builds against system libraries and to support more estoric architectures.

Please note that support for alternative VM solutions (CACAO, Shark, Zero) may be lacking in this release. Specifically, Zero/Shark are known not to work with the 2.2 release series. Patches are welcome; please contact the mailing list (distro-pkg-dev at openjdk.java.net) and/or file bugs (http://icedtea.classpath.org/bugzilla) under the appropriate component.
